Instance Method Details

#apply_updates(updates_path) ⇒ Hash

Applies all the updates from the given file system path.

Basically, requires all the files from the given directory with a .rb suffix, instantiates the class in the file, and calls ‘perform_update’ on it. This naturally requires that classes obey the default naming convention, i.e. a file named sample_update.rb should define a class named SampleUpdate.

Parameters:

  • updates_path (String|Pathname|Symbol)

Returns:

  • (Hash) —

    A hash or results; update => result
